| 2010-03-06 | util: Use bitshift arithmetic to unpack pixels. | José Fonseca | |
| All test cases pass now. | |||
| 2010-03-06 | util: Several fixes to clamping and test. | José Fonseca | |
| All tests pass here except util_format_b5g5r5a1_unorm_unpack_4ub, due to apparently a gcc 4.4.3 bug. | |||
| 2010-02-26 | util: Code generate functions to pack and unpack a single pixel. | José Fonseca | |
| Should work correctly for all pixel formats except SRGB formats. Generated code made much simpler by defining the pixel format as a C structure. For example this is the generated structure for PIPE_FORMAT_B6UG5SR5S_NORM: union util_format_b6ug5sr5s_norm { uint16_t value; struct { int r:5; int g:5; unsigned b:6; } chan; }; Not used everywhere yet because it seems compiled code is slower than bitshift arithmetic by some misterious reason. So we should generate bitshift arithmetic at least for the simple UNORM pixel formats. | |||
